the resultant resistance of two resistance wires in series combination is 108 ohm and in parallel combination is 24 ohm. find the value of individual resistance

Answers

Answer 1

Answer: Call the two resistors 'x' and 'y'.

In series, the resultant resistance is their sum: x + y = 108
Notice that y = 108 - x. I think we'll use that very soon.

In parallel, the resultant resistance is (their product) / (their sum) = xy/108 = 24

Multiply each side by 108:

xy = 2,592

Substitute for 'y' :

x(108 - x) = 2,592

108x - x² = 2,592

-x² + 108x - 2,592 = 0

x² - 108x + 2,592 = 0

Use the quadratic formula to find:

x = 72 . . . then y = 108 - 72 = 36
or
x = 36 . . . then y = 108 - 36 = 72

The individual resistors are 36Ω and 72Ω .

Course TaskAs I sat under an Oak tree I recognized some similar comparisons to what Isaac Newton saw under his apple tree. I saw three different objects fall to the ground…an acorn, a leaf, and a small stick. I wondered how and why they fell the way they did. The stick fell from the very top of the tree and seemed to almost “slow down” about half way down. The acorn got faster all the way to the ground. Yet the leaf would just float back and forth in a calm rhythm like motion. Furthermore, I could see the moon sitting up in the sky just waiting to peak over the trees at dark. How is it that all objects are apparently affected by the earth’s gravity but they seem to respond differently? If gravity is a force that affects all objects…shouldn’t all objects respond the same? Interesting Phenomenon huh….Can you explain what is happening with each of these four objects (including the moon)?

Could anyone explain how to size of an image works in a pinhole camera?

Answers

An image of an object can be used to determine the object's size or the distance to the object. The ability of the human eye's lens to focus an image on the retina is aided by the eye's pupil (the eye's aperture), which acts as a pinhole camera.

All contraceptives prevent STIs true or false

Answers

False. Not all contraceptives prevent STIs.

Contraceptives are items used or taken to prevent conception. These are birth control pill, patch, ring, IUD, birth control shots, and condoms. Among these contraceptives, condoms are the only type of birth control that prevents STIs or Sexually Transmitted Infections.

All contraceptives prevent STIs is False because not all them are used in STI prevention.

What is contraceptives about?

Not all contraceptives prevent sexually transmitted infections (STIs). Only condoms, dental dams, and some internal condoms, such as the female condom, can help prevent the transmission of STIs.

Other forms of contraception, such as birth control pills, the patch, the ring, and the shot, do not protect against STIs. This is because they work by preventing ovulation or by thickening the cervical mucus, which makes it more difficult for spermto reach the egg. They do not prevent the transmission of STIs because they do not block the exchange of bodily fluids, which is how STIs are spread.

So, the answer is false.
